SeqX: Residue co-locations in a nucleo-protein complex (1A6Y). Residue Contact Map of a nucleo-protein complex (1A6Y) was generated by SeqX. Residue co-locations were detected within 6–9 Å radiuses from C_alpha amino acid and C₁' nucleotide atoms and it was not necessary to use the closest neighbor exclusion option, Ex (+/-): 0. The different kind of molecular co-locations and the main features of the protein secondary structure is color coded. It is possible to zoom in the central portion of the map (middle) and navigate it in optional directions using the mouse (left and right part of the figure). The primary structure (sequence) is readable along the x and y axis in the magnified maps and it is possible to highlight individual co-locations (green letters).
